mAMMU,
I don't see any walktrhoughs available yet on line, nor any strategy guides, there is something to consider about using either with this particular game though...
I just started playing this one and Storm of Zehir is exactly what the developers say it is. To quote the manual (which I did more fully
here ) :
...What you are about to play might not be the game you’re expecting....
The game is more along the lines of the older RPG's and allows you to not only build your own party from the ground up, it also gives you more freedom of play. While most RPG's that use the D&D rulesets have the computer as the DM in the background, as I mention in my earlier post the "computer as Dungeon Master" feels much more prevalent here than in past games. While a walkthrough may help with certain specific quest oriented difficulties, following one too closely will in a way defeat the purpose of this particular game's design, which is to give back to the player more freedom in the gaming world.
While not the perfect substitute for a walkthrough the manual does provide some good information to begin with and the folks over at Bioware's
NWN2: Storm of Zehir forums are a friendly crowd that can help out as the need arises as well if you want to jump in before a walkthrough is published.
EDIT: One other thing I think I should mention that I didn't in my ealier post is that this is not a direct continuation of the last expansion. There are some references to it, but it is a game all it's own.
